Method.—On March 1, 1918, small quantities of wheat 
harvested in 1917 were sealed in three glass bottles—A, B, 
and C, respectively. 
Test (1).—At the end of fourteen days the wheat in 
bottle A was planted on damp soil under a sheet of glass. 
Result.—The grain germinated freely. 
Test (2).—At the expiration of twenty-eight days the 
wheat in bottle B was planted on damp soil under glass. 
. Result——The grain grew freely. ; 
. Test (3).—On September 13, just 196 days after being 
el in bottle C, the grain was planted on damp soil under 
ass 
Result.—The grain grew freely. ; 
Conclusion.—The result of these three trials, which mark 
Progress in a long series of experiments, goes to show that 
eat may be stored in hermetically sealed receptacles for a 
considerable period without impairing its vitality. 
XPERIMENT 4.—To prove that dry grain can be safely 
stored in an atmosphere rich in gas for considerable 
Periods without injury to the vitality of the ie 
Method.—Small quantities of grain harvested in 1917 
displaced air passed through a second tube into lime-water. The 
lime-water was used to test the quality of the air expelled 
3 from the bott]e containing the grain. When the overflow was 
"ich in CO, the bottle was carefully sealed. ; 
Test.—At the end of fourteen days, twenty-eight days, 
and 196 days, respectively, the grain in the three bottles was

Result, Bottle B.—The grain grew well after experiencing 
the effects of CO, gas for twenty-eight days. - 
Result, Bottle C.—At the end of twenty-eight weeks t 4 
grain appeared not to have suffered as a result of confinemen
